To all 'whom it may concern.'

Be it known that I, GRovER C. GILSTRAP, a citizen of the United States, residing at Claiiin, in the county of Barton, State of Kansas, have invented certain new and useful Improvements in Weather-Strips; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in weather strips, and particularly to weather strips for use in connection with windows.

The principal object of the invention is to provide a novel and cheap weather strip which can be quickly and easily applied to a window sash and frame by an unskilled person, and without the use of special tools.

Another object is to provide a device of this character which is slidable to effectively close the cracks at the side of the window for the purpose of excluding drafts of air and dust.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing,

In the drawing Figure 1 is a fragmentary elevation of a window sash and frame, showing my weather strip applied thereto; Fig. 2 is a similar view showing the sash in partly raised position; Fig. 3 is an enlarged transverse sectional view on the-line 3--3 of Fig. 1; and Fig. 4 is an enlarged vertical section on the line 4 4 of Fig. 1.

Referring particularly to the accompanying drawing, the weather strip at the vertical sides of the windows comprises the two parts A and B. The part A consists of a strip of metal including a flat body portion 10 which is secured to the vertical inner face of the side of the sash by means of the screws 11. The end of the body portion adjacent the inner stop beadof the window `frame 12 is directed away from the sash at an acute angle, as shown at 13, and the edge of this portion is then curved as. at 14, to extend inwardly toward the body portion 10. The portion B of the weather strip includes a flat body portion 15 secured to the vertical face of the stop bead 12 adjacent the sash.

.as at 19, and receives the portion 14 of the member A therein. It will be noted .that the portion 14 snugly engages in the curved portion of the member BA between the points 20 and 21 so that danger of air and` dust getting into the house through the crack between the sash and the window frame is eliminated. The members A and B are formed of metal possessed of a certain amount of resiliency thus permitting of the member A being securedl to the sash, and the member B to the stop bead 12 in such manner that more or less frictional contact can be produced between the interlocking portions of the members.

It will be noted that when the sash is raised or lowered, the portions of the member A will readily slide within the engaged portion of the member B, so that a `close contact is had between the parts at all time.

Carried by the lower rail of the upper sash 22 is an elongated strip of metal which is V-shaped in cross section, as shown at 24, while a similar but slightly smaller strip 25 is secured to the upper rail of the lower sash 26, these strips being arranged to interlock or nest when the sashes are in closed position to effectively close the crack at the midrail and thus exclude air and dust at this point.

While I secured to the inner faces of the sash and frame, itv will be readily understood that I may apply them to the outer faces with equal, if not greater efficiency. Strips simllar to those shown at 24 and 25 may be applied to the top of the upper and at the bottom of the lower sash.

What is claimed is:

A weatherstrip comprising a pair of metallic strips secured respectively to the sash have shown the strips A and Bv and frame of a window, one of said strips the sash and frame and rolled to extend inwardly toward said margin, the other strip having its unattached margin extended in the same direction as the iirst margin and engaging therewith, the last-named margin being snugly tted into and slidable within Said rolled portion. i

In testimony whereof, I aiix my signature, in the presence of two witnesses.
